Objective: This study elucidates the association between acceptance, mindfulness, and psychological well-being in a community-based sample participating in a Mindfulness-Based Stress Reduction (MBSR) program. Method: Participants (n = 52) completed an 8-week MBSR program at an academic medical center. Participants completed the Profile of Mood States (POMS), Mindfulness Attention Awareness Scale (MAAS), and Acceptance and Action Questionnaire (AAQ-II) at pre- and post-MSBR programs. Results: Serial mediation analysis suggested that changes in mindfulness preceded changes in acceptance, which improved well-being (indirect effect = −6.57, 95% confidence interval [CI; −13.38, −1.57]). Participants with low pre-MSBR acceptance significantly increased acceptance and well-being (p <.001). Moderated mediation models suggested that the pre-MBSR acceptance level moderated the mindfulness-acceptance and the acceptance-well-being link. Conclusions: Acceptance may be related to mindfulness and pre-MSBR acceptance may differentially affect outcomes. Limitations include a nonclinical sample and a lack of a control group. Future research may examine mindfulness “dose” and other mechanisms that facilitate improvements in outcomes.
